Question 1

What does +.25 mean in the product name?

Accepted Answer

The +.25 indicates that this bearing set is 0.25mm larger than the standard size. These bearings are typically used when the crankshaft has been machined undersize during a rebuild. Using an oversized bearing restores the proper oil clearance.

Question 2

What happens if I install the wrong size main bearings?

Accepted Answer

Installing the wrong size main bearings can lead to serious engine damage. If the bearings are too small, there won't be enough oil clearance, causing the bearing to overheat and potentially seize. If the bearings are too large, you'll have low oil pressure, which can also damage the engine.

Question 3

Do these bearings come with installation instructions?

Accepted Answer

Main bearing installation requires specific knowledge and tools. Refer to the manufacturer's installation instructions and torque specifications for proper installation. If you're not comfortable with this type of work, it's best to have a professional mechanic install them.
